(Wild Garlic)

This is an enormous and diverse plant genus. The onion family contains about 1250 species of herbaceous bulbous or rhizomatous plants that can be found across north temperate climates worldwide. All are perennials and cultivated forms are either grown for their ornamental flowers and foliage or as crops that yield edible greens and bulbs, such as onion, garlic, chive and leek. Species may be deciduous or evergreen and some are ephemeral.

Ornamental onions run the gamut from tiny groundcovers...
